Research continues in the field of Alzheimer’s disease prevention, and new information comes to light almost weekly.
While geneticists are looking for pre-programmed links to developing the disease, other scientists have found that lifestyle indicators bear much of the risk as well- and those can actually be controlled.
For instance- there is a very strong link, newly discovered, between Alzheimer’s and high blood pressure.
In a recent study out of VA San Diego Healthcare System, researchers recently confirmed what others had suspected but had no proof of until now. Scientists there found that high blood pressure is directly linked to Alzheimer’s disease.
In the study, scientists looked at health indicators for people aged 55 to 100. What they found was that for those with hypertension in the middle-age group, (defined as age 55-70), a specific biomarker that is tied to Alzheimer’s disease is present. As the vascular damage increases, so does the biomarker.
The study looked at pulse pressure, which is found by subtracting diastolic (bottom) pressure from systolic (top). The higher the pulse pressure was in the participants, the higher the concentration of amyloid beta or p-tau proteins in their spinal fluid. These are the biomarkers that are found to be responsible for cell death in the brain that leads directly to Alzheimer’s.
Reasons to act immediately to reduce high blood pressure mount almost daily, as the new study reveals. There are easy, drug-free ways to do it that don’t involve dangerous side effects or drastic lifestyle changes.
The point on pulse pressure, the number for which is arrived at by deducting the diastolic figure from that of the systolic figure, does not really make sense to me. You say that the larger the difference the greater the risk of contracting Alzheimer’s Disease but this would appear to suggest that, by way of example, a blood pressure reading of 180 over 140 is more “desirable” than one of 120 over 75, since the difference of the latter figures is greater than that of the former! Can this really be correct?!
